Formula and worked example

Lecture Attendance Calculator method: Current attendance = attended classes ÷ classes held × 100. A target calculation solves the same ratio after adding future attended or missed classes.

Worked example: With 72 attended classes out of 100 and a 75% target, attending the next 12 gives 84 ÷ 112 × 100 = 75%.

Important limit: Use the class count and target recognized by your institution; this arithmetic does not decide condonation, leave, or attendance policy.
